MACHINE FOR PUNCHING HOLES IN JACQUARD CARDS.

SPECIFICATION forming part of Letters Patent No. 445,340, dated January2'7, 1891.

Application filed April 21,1890. Serial No. 343,808. (No model.)

To ctZZ whom it may concern.-

Be it known that I, OTTO V. SCHAUM, of the city and county ofPhiladelphia, State of Pennsylvania, have invented a certain new anduseful Improved Machine for Punching Holes in Jacquard Cards, of whichthe following is a true and exact description, reference being had tothe accompanying drawings, which form a part of this specification.

My invention relates to machinery for punching the holes in Jacquardcards; and has for its object to improve such machinery and render itmore easy and convenient to operate.

My improvements will be best understood as described in connection withthe drawings, which illustrate the construction of a machine embodyingthem, and in which- Figure 1 is a perspective view of the said machine.Fig. 2 is a perspective view of the rods or punches used to force thelockingbolts back to an inoperative position, and their attachments. Oneof the punches which operate upon the card, the bolt which secures thesaid punch in operative position, and the key by which the bolt isoperated are also shown. Fig. 3 is a plan view of myimproved machine,taken on the section-line 1 y of Fig. 5, or along the top of plate D,said plate bein g also broken away, as indicated by sectionlines, toshow some details of construction. Fig. 4 is a side elevation of themachine, taken on the line it w of Fig. 5; and Fig. 5 is a frontelevation taken on the line 00 00 of Fig. 4.

A is the frame of the machine; A, the table before which the operatorstands; B B, plates secured one above the other, and having a recess 11formed between them to receive the cards. .The plates B and B areperforated, as shown at h and b, so as to permit the punches to passthrough them.

As shown, the plates B B are secured together by means of the threadedbushings O C, and they are fastened to the pad or frame of the machinein any convenient way.

D D are two iron plates, which together form the movable head ofthemachine. This head is formed with a series of vertical perforations dd, corresponding in position with the perforations b l) in the plates BB. The parts (1 of these perforations are smaller in diameter than theparts (Z. Sockets (Z are formed at each end of the movable head toreceive punches, which are secured therein so as to always move up anddown with the movable head. Leading into the perforations (Z are twoseries of horizontal perforations or holes, one series, indicated by theletters (Z leading from the back of the movable head, and the otherseries, indicated by the letters (1, leading from the front of themovable head.

As shown, the two plates D and D are secured together by means of theguide-rods E E, which pass through perforations d d in the said platesand clamp them together by means of the rings 0, resting against thelower plate D, and nuts c,screwing on threaded ends of the rods E andpressing against the upper part of the plate D. These guide-rods E movein the bearings C of the lower head B B, keeping the movable head inline with it. Horizontal perforations d d are also formed in each end ofthe movable head, for the purpose hereinafter describod. The movablehead is actuated by means of pitmen or connecting-rods F F, secured toit, as shown, and the cams G G, attached to the driving-shaft H. Theshaft II is driven by thepulley I and clutch J. The said pulley runsloosely upon the shaft II, except when the clutch J is actuated so as toconnect them.

' I have not thought it necessary to describe the construction of theclutch shown, as any convenient clutch may be used and arranged so as tonormally disconnect the pulley and shaft and to connect them only whenthe clutch-actuating device such as is indicated at J is operated.

K K, &c., are the card-punches formed with an enlarged head andproportioned so that the punches will pass freely through theperforations cl, while their heads will rest upon the rim formed betweenthe perforations d and its enlarged continuation (Z. The portion at ofthe perforation is sufficiently long to permit the punches to. move upin it for a distance suliiciently great to prevent their ends passingthrough the slot b when the movable head is in its lowest position.

M M, &c., are bolts, which are inserted in the perforations (i in themovable head.

They are formed with an offset m, which, by engagingwith abar msecuredacross .the lower part of the perforations (1 will prevent themcoming out of said perforations, and in order to prevent them frommoving too freely in the perforations, I form in each belt a recess m,in which I place a light spring m which presses against the upper partof the perforations (Z and serves to steady the bolt therein.

L L, &c., are rods which pass through the perforations (Z in the backof. the movable head and at their rear ends are secured to a bar L, fromeach end of which rods L L project and pass through the perforations din themovable-head. On the end of the parts L 'ofithese rods, whichproject to the front of theh-ead handles L are secured, and about said.partsi L, which are, as shown, smaller than theparts L spiral springs Lare secured whichq act-to press the rods-and the bar L,.which .they'carry, backward.

z-To the extent above described the machine in its general features isold, and my present invention consists of the hereinafterdescribedimprovements upon the said machine. To the. upper part of themovablehead I secure-one or. more rodsn n,-preferably two, arrangedone-in'front of the other, as'shown. They are attached vto the movablehead by means of the brackets N N, and I pivot upon these rods keys 0O,.the lower ends of which rest. .against the ends of the bolts M, whiletheirinpper ends are properlyformed-to enableerthem to be -operatedas,for-instance, like a1type-writer.and it is preferable-to arrange thesekeys on the rods n n alternately, so-as to give them thestaggeredarrangement shown, by which the apparatus -:is rendered more compact andmore easilybperated. Each. of the. keys will of'course be marked toindicatethebolt and punch which it controls.

The operation of the machine is as follows: The operator sets themachine for the work itisto perform by pressing down upon the keys whichgovern the punches which he desires to bring into operation. Each key,when pressed, pushes its corresponding bolt until its inner end-extendsacross the topof'the perforation cl and above the head k of the punchcontained in said perforation. The desired pattern of the cardhaving'thus been provided for, the operator slips a blank card into thegroove b and-then by actuating the clutchlever J connectsthedriving-pulley I with the shaft H, so as to rotate said shaft, and bymeans of cams G and connecting-rods F draw down the movable head. As-thehead moves down, the punches K of course move with it until they comeinto contact with the blank card,when those punches over which the boltsM extend pass through the card, while those which are not bolted arefree to rise in the perforation d, and do risetherein as the movablehead descends, making no perforation claim as new, and desire to secureby Letters Patent, is
